Answer:

Solution: $4\frac{3}{4}$ , 3.5, -15, 5

Not a solution: 129 and $10\frac{2}{3}$

Step-by-step explanation:

20 ≥ 5 + 3x

3x + 5 ≤ 20

3x ≤ 20 - 5

3x ≤ 15

x ≤ 5

x must be LESS than or EQUAL to 5

at Michaels auto shop, it takes him 15 minutes to do an oil change and 24 minutes to do a tire change. let x be the number of oi

Roman55 [17]

Answer:

Step-by-step explanation:

At Susan's auto shop, it takes her 12 minutes to do an oil change and 18 minutes to do a tire change. Let x be the number of oil changes she does. Let y be the number of tire changes she does.

Using the values and variables given, write an inequality describing how many oil changes and tire changes Susan can do in less than 3 hours (180 minutes).

Answer provided by our tutors

The total time that Susan needs to change x oil changes and y tire changes is less than 180 min.

The time needed for x oil changes is 12 * x.

The time needed for y tire changes is 18 * y.

The total time is the sum of the above times and needs to be less than 180 that is

12 * x + 18 * y < 180 divide both sides of equation by 6

12/6 * x + 18/6*y < 180/6

2*x + 3*y < 30

2*x < 30 - 3*y divide both sides by 2 to get the inequality for x

x < 30/2 - 3/2*y = 15 - 1.5 y < 15 that is x < = 15

2*x + 3*y < 30

3*y < 30 - 2*x divide both sides by 3 to get the inequality for y

y < 30/3 - 2/3 *x = 10 - 2/3*x < 10 that is y < = 10

Also we can write x + y < x+ 3/2 * y < 15.

Susan can do not more then 5 oil changes and not more then 10 tire changes or all together she can do not more then 15 total of oil and tire changes.

Just do this problem but with Michael

Lisa completed the table to describe the product of a mystery one - digit factor and factor and each numbers

deff fn [24]

Answer: part A is 0, 2, 4, 6, 8 and part B is Because the products all are even, the mystery factor must also be an even number. We have selected all of the even one-digit numbers.

Step-by-step explanation:

So, the number you need to find is between 0 and 9, because is a 1-digit number. For example, it cannot be 10 because 10 is a 2-digit number.

So, the number could be like 0,1,2,3...etc

In the table, the "X" in the left upper corner is the symbol for multiplication.

The "?" in the left lower corner represents the mystery number.

The table shows that the product of the mystery number and 1,2,3,4 and 5 is always an even number

For example, the product of the mystery number and 3 is even.

That means that our mystery must be even.

So, we know that the mystery number is between 0 and 9 and it must be even.

Therefore, the mystery number can be one of the following numbers:

0, 2, 4, 6, 8
